Vitim (Russian: Вити́м; Yakut: Битиим, Bitiim) is an urban locality (an urban-type settlement) in Lensky District of the Sakha Republic, Russia, located 229km (142miles) from Lensk, the administrative center of the district,[1] on the left bank of the Lena River at its confluence with the Vitim River. As of the 2010 Census, its population was 4,376.
Vitim was first mentioned in 17th-century historical sources as a winter fort and later as a trading fort.[2] By the mid-19th century, the settlement spread along a 2km (01miles) section of the river, with a population of about 250 inhabitants, who made a living from river trade, fishing, hunting, gold mining, and handicrafts. During the Imperial era, it served as a place of political exile; H. Leivick was exiled here in 1912–1913.
Urban-type settlement status was granted to Vitim in 1958.
Within the framework of administrative divisions, the urban-type settlement of Vitim[3] is incorporated within Lensky District as the Settlement of Vitim. As a municipal division, the Settlement of Vitim is incorporated within Lensky Municipal District as Vitim Urban Settlement.[4]
Vitim's development is being influenced by the development of the Talakan oil field.
Vitim is served by the Vitim Airport.[5]
Vitim has a subarctic climate (Köppen climate classification Dfc) with severely cold winters and warm summers. Precipitation is quite low but is somewhat higher in summer than at other times of the year.
